Cell apoptosis induced by different groups, as determined by fluorescence microscopy. Values, quantified by random counting of acridine orange-ethidium bromide-stained cells, were mean ± standard deviation of data from the three independent experiments. Percentages represent the different stages of cell death. (P < .05, as determined by ANOVA single factor).
